Abstract
The utility model relates to a multi-spark plug engine cylinder head which comprises a cylinder head, spark plug installation holes, air inlets and air outlets, the spark plug installation holes and the air inlets and the air outlets are all arranged on the cylinder head, the multi-spark plug engine cylinder head is characterized in that two of the four spark plug installation holes are respectively positioned on the same one plane at one sides of the air inlets and the air outlets, and the other two spark plug installation holes are positioned on the same plane of the other sides of the air inlets and the air outlets. Due to adoption of the technical scheme, the multi-spark plug engine cylinder head has the advantages of being simple in structure and convenient to machine; two spark plugs are arranged at two sides of the air inlets and the air outlets and used for ignition at the same side, the burning area and the explosive force are obviously increased, the burning is more sufficient and more thorough, the emission is cleaner and the ignition safety coefficient is high.
Description
Technical field
The utility model relates to a kind of cylinder head, particularly a kind of cylinder of motorcycle engine.
Background technique
Existing motorcycle engine generally arranges a spark plug mounting hole at cylinder head, spark plug is installed in the spark plug mounting hole, carry out single spark-plug ignition, the explosive power of single spark plug a little less than, make in the firing chamber from the burning of the combustible gas of spark plug away from and will lag behind, velocity of combustion is slow, it is insufficient to burn, increase fuel consumption, the discharging of tail gas does not reach requirement, under high-temperature and high-pressure conditions, spark plug is easy to ablated, cause the ignition performance of spark plug to reduce, motor can't be worked when the ignition performance of the spark plug in the single spark-plug ignition completely loses, the problem that exists in order to solve single spark-plug ignition, at present, the employing dual ignition is also arranged, at cylinder head two spark plug mounting holes are set, two spark plug mounting holes be relative be installed in into, on the plane of the exhaust port left and right sides, in two spark plug mounting holes, spark plug is installed respectively, during work, the igniting of two spark plugs forms two detonation points, although can improve certain velocity of combustion, the ignition point of two spark plugs is far away
Two spark plugs are in separately one side igniting, explosive power also a little less than, when the firing time of two spark plugs is inconsistent, also can makes from the burning of the combustible gas of spark plug away from and will lag behind, velocity of combustion is slow, it is insufficient to burn.
Summary of the invention
The purpose of this utility model just provides that a kind of burning is more abundant, more complete, discharging is cleaner and igniting safety coefficient much higher spark plug engine cylinder head.
The purpose of this utility model is to realize by such technological scheme, it includes and comprises cylinder head, spark plug mounting hole and inlet and outlet hole, spark plug mounting hole and inlet and outlet hole all are arranged on the cylinder head, it is characterized in that: spark plug mounting hole is four, wherein two spark plug mounting holes all are positioned on the same plane of inlet and outlet hole one side, and two other spark plug mounting hole is positioned on the same plane of inlet and outlet hole opposite side.
The utility model is installed in spark plug in the spark plug mounting hole first, because both sides, inlet and outlet hole all have two spark plugs, during use, to form four detonation points, nearer with the ignition point of two spark plugs on one side, detonation point is larger, enlarged markedly burning area, obviously increased explosive power, accelerated velocity of combustion, made burning more abundant, more complete, make discharging cleaner, when the ignition performance of an one spark plug completely lost, other spark plug also can continue to use, and safety coefficient is high.
Owing to adopted technique scheme, the utlity model has advantage simple in structure, easy to process, it all adopts dual ignition plug lighting a fire with one side in both sides, inlet and outlet hole, enlarged markedly burning area, obviously increased explosive power, made that burning is more abundant, more complete, discharging is cleaner and the igniting safety coefficient is high.
Description of drawings
Description of drawings of the present utility model is as follows.
Fig. 1 is structural representation of the present utility model.
Among the figure: the ⒈ cylinder head; The ⒉ spark plug mounting hole; The ⒊ inlet hole; The ⒋ exhaust port.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples: as shown in Figure 1, the utility model comprises cylinder head 1, spark plug mounting hole 2 and inlet and outlet hole 3,4, spark plug mounting hole 2 and inlet and outlet hole 3,4 all are arranged on the cylinder head 1, it is characterized in that: spark plug mounting hole 2 is four, wherein two spark plug mounting holes 2 are positioned on the same plane of inlet and outlet hole 3,4 one sides, and two other spark plug mounting hole 2 is positioned on the same plane of inlet and outlet hole 3,4 opposite sides.
The utility model is installed in spark plug in the spark plug mounting hole 2 first, because both sides, inlet and outlet hole all have two spark plugs, during use, to form four detonation points, nearer with the ignition point of two spark plugs on one side, detonation point is larger, enlarged markedly burning area, obviously increased explosive power, accelerated velocity of combustion, made burning more abundant, more complete, make discharging cleaner, when the ignition performance of an one spark plug completely lost, other spark plug also can continue to use, and safety coefficient is high.
